The natural border between North and South Korea is established by the 38th parallel. This geographical line divides the Korean Peninsula into two distinct nations. It has significant historical implications, marking the division that resulted from the Korean War, which ended in 1953. The area surrounding the 38th parallel is heavily militarized and includes the Demilitarized Zone (DMZ), a buffer zone intended to reduce conflict between the two Koreas. The division has led to significant cultural and political differences, impacting the lives of millions.
